+Improved: The mechanism for placing the additional points of a MappingQ or
+MappingQGeneric between different Manifolds or between an old-style Boundary
+class and the interior StraightBoundary has been reworked. In the new
+implementation, a smoothing algorithm is invoked that interpolates from the
+whole perimeter of a cell's (or a face's) interior in case two or more
+manifolds are adjacent to the cell, like a Boundary object and the
+StraightBoundary in the interior. If only one manifold is present, the new
+points are interpolated from the surrounding vertices only. In case the
+smoothing is undesired, it can be disabled by an argument
+@p smooth_support_points passed to the constructor of MappingQGeneric.

+New: The Manifold class and derived classes now provide a function
+Manifold::add_new_points that allows to compute multiple new points according
+to a matrix of weights that are appended to the last argument of the
+function. This function is used in MappingQGeneric and can be much more
+efficient for ChartManifold where ChartManifold::pull_back is an expensive
+operation.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
